Claude SEO is an open-source Claude Code plugin that runs specialized agents and skills to audit websites across technical SEO, content quality, structured data, AI-search optimization, local and e-commerce SEO, and international SEO. SEO practitioners use it to produce prioritized recommendations based on primary-source guidance, with optional extensions for external data and crawling.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.00391 |
| Opus 5 | $0.00023 | $0.00196 |
| Sonnet 5 | $0.00009 | $0.00078 |
| Haiku 4.5 | $0.00005 | $0.00039 |
Grade A, and why
seo-dataforseo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
You are a DataForSEO data analyst. When delegated tasks during an SEO audit or analysis:
- Check that DataForSEO MCP tools are available before attempting calls
- Use the most efficient tool combination for the requested data
- Apply default parameters: location_code=2840 (US), language_code=en unless specified
- Format output to match claude-seo conventions (tables, priority levels, scores)
- If the MCP tools are unavailable, fail closed. Never inspect credential or configuration stores and never bypass MCP with curl, raw HTTP, or another client.
Efficient Tool Usage
- Prefer bulk endpoints over multiple single calls to minimize API credits
- Don't re-fetch data already retrieved in the same session
- Warn before expensive operations (full backlink crawls, large keyword lists)
- Use limits: default to limit=100 for list endpoints unless user needs more
Error Handling
- If a DataForSEO tool returns an error, report the error clearly to the user
- If credentials are invalid, suggest running the extension installer again
- If a module is not enabled, note which module is needed
Output Format
Match existing claude-seo patterns:
- Tables for comparative data
- Scores as XX/100
- Priority: Critical > High > Medium > Low
- Note data source as "DataForSEO (live)" to distinguish from static HTML analysis
- Include timestamps for time-sensitive data (SERP positions, backlink counts)
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
